초록

어린이의 맹출 중인 치아는 느슨한 치주 인대와 덜 석회화 된 치조골로 둘러싸여 있기 때문에 외상에 취약하다. 외상에 의한 치아의 완전 탈구는 상악 중절치에 가장 빈번하게 발생한다. 탈구된 치아의 재식 후 예후는 구강 외 보존 시간과 상태에 영향을 받는다. 외상 당한 전치의 예후가 불량한 경우 소구치의 전치부 자가 이식은 임플란트 보철이 어려운 성장기 청소년 환자의 적절한 치료 방법으로 받아들여진다. 이 증례 보고는 외상당한 전치와 불량한 구강 위생 및 심한 총생을 가진 청소년 환자에서 치근이 완성된 소구치의 전치부 자가 이식을 통한 심미적 회복의 결과를 기술하고 있다. 복잡하고 어려운 구강 문제의 개선을 위해 포괄적이고 장기간에 걸친 치료가 진행되었다.

The loosely structured periodontal ligament and low mineralized bone surrounding erupting teeth provide minimal resistance to an extrusive force. The maxillary central incisors are the most frequently avulsed due to trauma. The prognosis of replanted teeth is affected by extra-alveolar period and conditions. Implant-supported restorations are contraindicated in adolescent patients with poor prognosis traumatized teeth. Autotransplantation of premolar to the anterior region provides a viable treatment alternative. This case report describes the autotransplantation of premolars and esthetic rehabilitation in a teenage patient with traumatized incisors, poor oral hygiene, and severe crowding. Comprehensive and long-term treatments were performed to improve complex and challenging oral problems.
